invalid license
this error comes on every ea demo that I want to test.
Same with the EAs which you bought from the Market: delete them from Metatrader and after that - install once again by using same Metatrader.
Yep I know it only works on strategy tester only, I did uninstall and install them again, I also did this second account to try again, same thing...
As I see - you are using beta build 5055 of MT5.
It is better to download MT5 from the broker's (your broker') website - because the brokers are proposing the stable builds only (if I am not mistaken - the latest stable build is 4755).
---------------
By the way, I backtested demo version of one EA (from the Market) - and MT5 does not ask me for any license ... because demo EAs are not having any license at all -

Tester - "Market\[name of the EA].ex5 64 bit demo version
same think, from everywhere I download, I get the same build, 5055
The brokers should provide the latest stable build (in case you did not connect to MetaQuotes-Demo server).
The latest stable build which I have installed - build 4755.
So, ask your broker for support.

As to next stable build so it was the discussion on Russian forum that the next stable build will be on Friday -

Hi, few weeks ago I installed MetaTrader 5, testing some strategies everything fine, after the friday update, simply doesn't work to test strategies.
1. I delete everything from %appdata% related to MetaTrader
2. Installed again and still nothing
